Enzyme Assay Guided Isolation of an α-Amylase Inhibitor Flavonoid from Vaccinium arctostaphylos Leaves
The management of postprandial hyperglycemia is an important strategy in the control of diabetes mellitus and complications associated with the disease, especially in the diabetes type 2. Therefore, inhibitors of carbohydrate hydrolyzing enzymes can be useful in the treatment of diabetes and medicinal plants can offer an attractive strategy for the purpose. Vaccinium arctostaphylos leaves are c...

متن کاملIsolation of Phytoconstituents from the leaves of Murraya koenigii Linn
Fractionation of petroleum ether partitioned ethanol extract and crude petroleum ether extract of the leaves of Murraya koenigii Linn (Rutaceae) led to the isolation of 5,8-dimethyl furanocoumarin (1) and 1-al, 3[6’, 6’ dimethyl 5-hexene] carbazole (2) and β-sitosterol (3). Their structures were elucidated by spectroscopic methods such as UV, IR, NMR and LCMS. All the compounds were isolated fo...
متن کاملIsolation and Purification of Amylase from Sugarcane Leaves
Investigations were made concerning the number and properties of amylase in sugarcane leaves. Enzymes were extracted froin leaf samples which had been frozen, lyophilized, and ground to a fine powder. Techniques of differential solubihty, gel filtiation, and papei electrophoresis were employed to remove amylase from the crude extracts. Solubility studies showed that amylase was moderately preci...
متن کاملExtraction and isolation of Caffeine from tea leaves
General background and overview of the experiment: Humankind has historically used advantageous compounds derived from plants and animals. For instance, various extracts from plants have been used as teas, potions, medicines and poisons. Though these extracts can contain a mixture of many different chemicals, often only one or few are responsible for the activity of the extract. For decades suc...
